After 3.3M4, Modeling builds [https://bugs.eclipse.org/bugs/show_bug.cgi?id=170831 no longer ran their JUnit tests], due to changes in the way Eclipse packages its startup jars. I had thought the fix was trivial, but unfortunately [https://bugs.eclipse.org/bugs/show_bug.cgi?id=170831#c3 there's more to it than is explained below]. I'll update this document when I find a solution.
